Description

  The present invention relates to a tactile presentation device that presents a tactile sensation such as a warm sensation or a cold sensation, and more particularly to a tactile sensation presentation device using a thermoelectric element.

  In recent years, with the widespread use of devices that realize VR (virtual reality), attention has been focused on techniques for electrically and mechanically reproducing human tactile sensations. Japanese Patent Application Laid-Open No. H10-228561 describes a temperature sensation presentation device that reproduces an arbitrary temperature sensation using a Peltier element.

Japanese Patent Laid-Open No. 7-72018

  In order to reproduce an arbitrary temperature sense using a Peltier element, it is necessary to detect and control the temperature of the Peltier element. In the apparatus described in FIG. 7 and FIG. 8 of Patent Document 1, a temperature detection sensor is provided on the surface of a Peltier element with which a finger or the like comes into contact. However, if the sensor is affixed to the part that comes into contact with the finger, the sensor is likely to come off during repeated use, or wear and the like are likely to occur, which has the disadvantage of low durability. is there. There is also a disadvantage that the unevenness by the sensor gives a sense of discomfort to the touch.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a tactile sensation presentation apparatus capable of suppressing a decrease in durability and presenting a good tactile sensation without a sense of incongruity.

  A tactile sensation presentation apparatus according to the present invention includes a contacted surface that can be contacted by a tactile presentation target, a thermoelectric conversion unit that generates cold or heat transmitted to the contacted surface, and a temperature sensor that detects a temperature of the contacted surface. Have The thermoelectric conversion unit includes at least one thermoelectric member that generates a temperature difference between the first heat transfer member and the second heat transfer member based on the first and second heat transfer members and the supplied power. Element. The contacted surface is formed on the surface of the first heat transfer member, or is formed on the surface of another heat transfer member that contacts the surface of the first heat transfer member. The temperature sensor is located outside a region where the contacted surface is formed on the surface of the first heat transfer member, or outside a region contacting the other heat transfer member on the surface of the first heat transfer member. Be placed.

  According to this configuration, since the temperature sensor is arranged outside the region where the contacted surface is formed on the surface of the first heat transfer member, a tactile sense presentation target such as a finger does not directly touch the temperature sensor. . Thereby, durability improves compared with the case where the tactile sense presentation object touches the said temperature sensor directly. In addition, there is no sense of incongruity in tactile sensation due to a tactile sensation target directly touching the temperature sensor.

  In addition, according to this configuration, the temperature sensor is arranged outside the region in contact with the other heat transfer member on the surface of the first heat transfer member. Adhesion with the heat member is improved, and the cold or warm heat of the thermoelectric element is easily transmitted to the contacted surface.

  Preferably, the first heat transfer member may have a plate shape. The thermoelectric element may abut on one surface of the first heat transfer member. The contacted surface is formed on the other surface of the first heat transfer member, or formed on the surface of the other heat transfer member in contact with the other surface of the first heat transfer member. Good. The temperature sensor may be disposed on the one surface of the first heat transfer member.

  According to this configuration, since the temperature sensor is disposed on the one surface of the first heat transfer member where the contacted surface is not formed, a tactile sense presentation target such as a finger does not directly touch the temperature sensor. . Thereby, a sense of incongruity of touch does not occur and durability is improved.

  Further, according to this configuration, since the other heat transfer member abuts on the other surface of the first heat transfer member having a plate shape, the first heat transfer member and the other heat transfer member are in contact with each other. The member is easily brought into contact with a large area, and the cold or warm heat of the thermoelectric element is easily transmitted to the contacted surface.

  Suitably, the said tactile sense presentation apparatus may have a heat sink member which suppresses the temperature change of a said 2nd heat transfer member. The second heat transfer member may have a plate shape. The first heat transfer member and the second heat transfer member may be arranged to face each other. The thermoelectric element may contact one surface of the second heat transfer member. The heat sink member may abut on the other surface of the second heat transfer member. Two detection terminal portions for connecting two detection wires for transmitting a detection signal of the temperature sensor may be formed on the one surface of the second heat transfer member.

  According to this configuration, the heat sink member contacts the other surface of the second heat transfer member, while the two detection terminal portions are formed on the one surface of the second heat transfer member. Accordingly, the second heat transfer member and the heat sink member can be brought into contact with each other over a wide area without being interfered by the two detection terminal portions.

  Preferably, the temperature sensor may be located between the two detection terminal portions in a plan view as viewed from a direction perpendicular to each surface of the first heat transfer member and the second heat transfer member.

  According to this configuration, since the area occupied by the two detection terminal portions and the temperature sensor in the plan view is small, the area for arranging the thermoelectric element is relatively large.

  Preferably, the first heat transfer member and the second heat transfer member may have a rectangular shape in the plan view. The two detection terminal portions may be arranged at an end portion of the second heat transfer member along one side of the rectangular shape.

  According to this configuration, since the two detection terminal portions are arranged at the end of the second heat transfer member along one side in the rectangular shape, the thermoelectric element is arranged in the plan view. The area for this is relatively large.

  Preferably, two driving terminal portions for connecting two driving wirings for supplying electric power to the thermoelectric element may be formed on the one surface of the second heat transfer member. The two drive terminal portions may be aligned with the two end portions of the second heat transfer member along the one side of the rectangular shape together with the two detection terminal portions.

  According to this configuration, the heat sink member contacts the other surface of the second heat transfer member, while the two drive terminal portions are formed on the one surface of the second heat transfer member. Accordingly, the second heat transfer member and the heat sink member can be brought into contact with each other over a wide area without being interfered by the two drive terminal portions. In addition, in the plan view, the two detection terminal portions and the two drive terminal portions are aligned with the end of the second heat transfer member along one side of the rectangular shape. A region for arranging the thermoelectric element becomes relatively large.

  According to the present invention, it is possible to suppress a decrease in durability and present a good tactile sensation without a sense of incongruity.

The drive circuit 80 includes an interface unit 90 that exchanges signals such as control commands and temperature detection values between a control unit 70 and a device (not shown) such as a host controller.

  For example, the control unit 70 performs a process of controlling the temperature of the contacted surface A in accordance with a control command input via the interface unit 90. That is, the controller 70 supplies power (for example, thermoelectric power) supplied from the thermoelectric element drive circuit 80 to the thermoelectric element 13 so that the temperature of the contacted surface A detected by the temperature sensor 20 approaches the temperature specified by the control command. The magnitude of the current flowing through the element 13 is controlled. In addition, the control unit 70 determines a range in which the temperature of the contacted surface A is predetermined in a steady state (a state where a finger or the like is not in contact with the contacted surface A) before and after the period in which the tactile sensation is presented. The process of controlling the temperature of the contacted surface A is performed so as to be maintained inside. Thereby, the response speed of the tactile sensation is increased.

Accordingly, the second heat transfer member 12 and the heat sink member 30 can be brought into contact with each other over a wide area without being interfered by the two detection terminal portions 51 and 52. The temperature change can be effectively suppressed. Since the temperature change of the second heat transfer member 12 is reduced, the temperature setting accuracy of the contacted surface A is improved, and a higher quality tactile sensation can be presented.

It is formed on the surface 121 on the Z1 side of the thermal member 12. Accordingly, the second heat transfer member 12 and the heat sink member 30 can be brought into contact with each other over a wide area without being interfered by the two drive terminal portions 53 and 54, and the temperature of the second heat transfer member 12 can be increased. Changes can be effectively suppressed.

<Second Embodiment>
Next, a second embodiment of the present invention will be described. 6-8 is a figure which shows an example of the tactile sense presentation apparatus based on 2nd Embodiment. 6 is a perspective view, FIG. 7 is a front view, and FIG. 8 is a plan view.

  The tactile presentation device according to the second embodiment is obtained by adding the third heat transfer member 40 to the tactile presentation device according to the first embodiment which has already been described, and other configurations according to the first embodiment. It is almost the same as the tactile sense presentation device. The third heat transfer member 40 is an example of another heat transfer member in the present invention. Below, it demonstrates centering around difference with the tactile sense presentation apparatus shown in FIGS.

  The third heat transfer member 40 is in contact with the surface 112 on the Z1 side of the first heat transfer member 11 and has a plate shape as shown in FIGS. A contacted surface A is formed on the Z1 side surface 402 of the third heat transfer member 40. A surface 401 on the Z2 side of the third heat transfer member 40 abuts on a surface 112 on the Z1 side of the first heat transfer member 11. The third heat transfer member 40 is, for example, a part such as a flexible substrate, a protective sheet member, a case or a housing that houses a tactile presentation device. Cold heat and warm heat from the first heat transfer member 11 are indirectly transmitted to the contacted surface A via the third heat transfer member 40.

According to the tactile sensation presentation apparatus according to the second embodiment having the above-described configuration, in addition to the same effects as those of the tactile sensation presentation apparatus according to the first embodiment, the following effects are further obtained.
(1) According to the tactile sensation providing apparatus according to the second embodiment, the temperature sensor 20 is disposed outside the region in contact with the third heat transfer member 40 on the surface of the first heat transfer member 11. Compared with the case where the temperature sensor 20 is disposed inside, the adhesion between the first heat transfer member 11 and the third heat transfer member 40 is improved, and the cold or warm temperature of the thermoelectric element 13 passes through the third heat transfer member 40. Thus, it is easy to be transmitted to the contacted surface A. Therefore, the temperature setting accuracy of the contacted surface A is improved, and a higher quality tactile sensation can be presented.

  In the embodiment described above, the temperature sensor 20 is disposed on the surface 111 on the Z2 side of the first heat transfer member 11, but the present invention is not limited to this example. For example, when the range of the contacted surface A is limited to a part of the surface 112 on the Z1 side of the first heat transfer member 11 (such as when the contacted surface A is limited by the resin case), the first transfer is performed. The temperature sensor 20 may be disposed in a region 112 on the Z1 side of the thermal member 11 and outside the contacted surface A. Also in this case, the tactile presentation target such as a finger can be prevented from directly touching the temperature sensor 20, so that the durability can be enhanced as compared with the conventional device, and the occurrence of a sense of incongruity of the tactile sensation can be prevented. Good tactile sensation can be presented.

  In the embodiment described above, the temperature sensor 20 is arranged at the end of the Z2 side surface 111 of the first heat transfer member 11, but in another embodiment of the present invention, the location away from the end of the surface 111. A temperature sensor may be arranged (for example, at the center).
